Product Details

Features

◆ Using inch pipe thread quick joint or copper pipe welding structure, easy to use, flexible installation, no need for special installation and fixation;

◆ The plug-in type or wire type connection mode is available for users to choose at will;

◆ Single-pole single-throw switch mode, normally open switch contact structure;

◆ Fusion-welded sealed stainless steel pressure sensor plus steel explosion-proof housing, safe and reliable;

◆ In the pressure range of 1305PSI~2610PSI (9～18MPa), the pressure value can be arbitrarily selected for manufacturing according to user requirements;

◆ The pressure parameters of the product have been set in the factory according to the requirements before leaving the factory, no need to set again, it can be used directly;

working principle

◆ This series of pressure switches are mainly manufactured by using the built-in stainless steel reversible diaphragm that can be reversed after sensing a certain pressure. When the diaphragm moves, a guide rod will drive the electrical contacts to
open. When the induced pressure drops below the recovery value, the pressure switch can automatically reset.

 

use

 

◆ This series of products are designed and manufactured specifically for refrigeration equipment that uses carbon dioxide as a refrigerant. The refrigeration system pressure is much higher than the special requirements of conventional refrigerants. They are used for high-pressure protection of the system; it is also suitable for high-pressure protection of various systems Equipment and tools with pressure greater than 800PSI (5.5MPa).

 

Design Parameters

 

◆ Working pressure range: 1305~2610PSI (9~18MPa)

◆ Bursting pressure: 10440PSI (72MPa)

◆ Ambient temperature: -30℃～+80℃

◆ System medium temperature: -50℃～+120℃

◆ Electrical specifications: the conventional electrical capacity is 125VA at 24Vac, and the conventional electrical capacity is 375VA at 120/240Vac

◆ Dielectric strength: AC700V/S between the disconnected contacts, AC2000V/S between the terminals and the shell
